※For countersunk screws, the overall length including the head is the designated length.

■Hex Socket Countersunk Head Bolt -JIS B 1194-
The countersunk head profile allows use in applications where protrusion is a concern. It provides greater clamping force than slotted bolts.
Also, like hex socket button head bolts, the hex socket size is slightly smaller than that of standard hex socket head cap screws. Also known as a countersunk cap screw. Features
This is a bolt with a hexagonal socket in a countersunk head. Tightening is performed using a hex key (Allen wrench).
Although classified as a bolt, it is most commonly used without a nut. Also referred to as a cap screw or socket screw.
Open-end spanners and wrenches used for tightening hex bolts require clearance space around the fastener, whereas a hex key requires no such clearance. This makes hex socket head cap screws ideal for work in confined spaces and for compact machine design.
Their appearance has also led to increasing use in design-oriented applications.

Applications
These fasteners offer advantages such as space-saving contributions to compact equipment design and high clamping force, and are widely used across many industries. They are particularly common in machinery and electrical components.
